We present two cases of central giant cell granuloma in the temporal bone. CT showed an enhancing tumor causing a smoothly margined temporal squamosa and floor of the middle fossa. External carotid angiograms showed tumor stain mainly supplied by the temporal branches of the internal maxillary artery. In one case, MR images showed a hypointense mass on both T1- and T2-weighted images that was thought to reflect the pathologic character of this lesion.
我们报告两例颞骨中央巨细胞肉芽肿。CT显示一强化性肿瘤,致使颞骨鳞部和中颅窝底边缘光滑。颈外动脉血管造影显示肿瘤染色主要由上颌内动脉的颞支供血。在一例中,磁共振成像显示在T1加权像和T2加权像上均为低信号肿块,这被认为反映了该病变的病理特征。
